REVOLVING WRENCH.

T 0 all whom it may concern:

Be it known that I, KARL WEISS, a citizen of the United States, residing at Waterbury, in the county of New Haven, in the State of Connecticut, have invented a new and useful Improvement in Revolving Wrenches, of which the following is a specification.

This invention relates to a wrench in which the aws and handles are rotatable with respect to each other and is the adaptation to a wrench of certain parts shown and described in a patent granted me May 7, 1907, No. 852,479, for revolving pliers.

The invention consists of certain novel changes in construction to adapt the invention to its new use which changes are hereinafter fully described, are pointed out in the claims and shown in the accompanying drawings, in which,

Figure 1 is a side elevation of the wrench complete. Fig. 2 is a top plan view. Fig. 3 is a side elevation with certain parts removed, and other parts in section showing the interior construction, the parts being in their normal position. Fig. 4 is a similar view, parts being shown in the position occupied when the aws are closed. Fig. 5 is a rear elevation of the housing and connected parts, the operating handles and parts carried thereby being removed. Fig. 6 is a detail perspective view of one of the handles, partly broken away. Fig. 7 is a detail perspective view of one of the jaws. Fig. 8 is a detail perspective view of one of the sections forming the housing. Fig. 9 is a detail view showing in perspective a connecting collar. Fig. 10 is a perspective view of one of the ratchets. Fig. 11 is a perspective view of a plunger. Fig. 12 is a perspective view of a rotatable sleeve.

The device consists essentially of operating handles A, a sectional housing A for the movable parts, movable aws A and a collar A designed to connect the handles A with the housing A.

The device also includes a sleeve B, which rotates freely within the housing and serves to hold the inner ends of the handles in their pro er position. The handles A, sleeve B, an collar A are constructed exactly like similar arts shown and described in the patent a ove mentioned.

Each handle A is provided at its inner end with a cam portion 0, and projecting pins C which form movable pivots for the handles. The sleeve B has upon opposite sides rear- Specification of Letters Patent.

Wardly extending lugs B, between which the cam portion of the handles rest.

Each jaw A is provided with an angled extension D, formed with a rib D upon its outer face, slotted as shown at D and provided with rack teeth D along its rear edge.

The housing A is cylindrical in form and is split into two sections each of which carries a forwardly extending plate E, grooved as shown at E to receive a rib D of one of the jaws. Each housing section is also perforated as shown at L and E and is provided with interior shoulders E Ratchets to cooperate with the racks of the aws consist of sleeves F, each of which carries a toothed segment F provided on one side with a proj ecting pin F In the revolving pliers I employ a cam disk to operate the jaws but in a wrench it is desirable that the gripping faces of the jaws should always remain parallel to each other, and I therefore replace the cam disk with a plunger consisting of a disk G provided upon its forward face with projecting angled lugs G. A pivot screw pin K passes through the perforations E of the housing and through the slots D of the jaws.

A pivot pin J has its ends secured in the perforations E and the coil springs H encircle said pin, the springs seating themselves in the recesses formed upon each section of the housing by the shoulders E one end of each spring bearing upon one of said shoulders and the opposite end upon the pin F of the adjacent ratchet. A collar A is threaded as shown at L to engage the exterior threads E of the housing and is roughened as at L so that it may be readily rotated.

The operation of the parts is as follows The ratchets being mounted upon the pin J, and in engagement with the rack teeth of the jaws will normally hold them apart as the ratchets are oppositely arranged and the springs H bear against the pins F of the ratchets. gether as shown in Fig. 4 the cam portions 0 will bear upon the rear face of the disk G which fits loosely within the sleeve B, and will move the same forward. The lugs G of this disk engage respectively the ends of the two ratchets, and the forward movement of this plunger will rotate the ratchets about their pivot pin in opposite directions and against the tension of the springs, thus sliding the extensions of the jaws in opposite directions and bringing the two jaws together.

By bringing the handles'A to- It will be understood that the extensions D of the jaws lie side by side sliding upon each other between the plates E of the housing, and it will also be understood thatthe sleeve B, rotates freely within the housing and housing and operable by the handles for bringing the aws together and springs adapted to normally hold them apart, the said jaws remaining at all times parallel to each other.

2. A wrench of the kind described comprising a housing and rotatable with respect to the housing, jaws movably held in said housing, operating handles loosely secured to the housing and means arranged within the housing and operable by the handles against spring tension for sliding the said jaws toward each other and at right angles to the longitudinal axis of the housing.

3. A device of the kind described consisting of a housing, oppositely arranged ratchets pivoted in said housing, jaws having rack teeth, the said teeth being arranged on a line at right angles to the gripping faces of the jaws, a plunger engaging simultaneously the ratchets, and the handle adapted to force said plunger forward.

4. In a wrench, a housing, a pivot pin, segmental ratchets carried by said pin, oppositely arranged pins carried by opposite sides of said ratchets, springs bearing respectively upon said pins, jaws loosely held in the housing and provided with rack teeth in engagement with the ratchets, a plunger having projecting lugs engaging opposite ends of the ratchet, and handles having cam portions adapted to force said plunger forward.
